<p>GChart is layered on top of GWT's standard widget set.
Specifically,
<tt>Image</tt> widgets (for curves) and <tt>Grid</tt> widgets (for
aligned text) are placed onto <tt>AbsolutePanels</tt> to render each
chart. Thus,
it works reliably cross-browser, fully exploits GWT's compiler
technology, and does not require proprietary
browser plug-ins, complex external JavaScript libraries, or a server
hit each time the chart changes.<p>
<p>

Though this approach has many advantages, high visual quality for
non-rectangular curve types isn't one of them. To fix this, GChart
lets you optionally bolt on an external GWT vector graphics library.
